Objective:To establish an HPLC method for the content determination of pseudolaric acid B
benzoic acid and salicylic acid in Fufang Tujingpiding. Method:The analysis was performed on the Agilent Zorbax SB C18(4.6 mm×150 mm
5 μm) column with the methol-0.09% formic acid as the mobile phase at 25℃. The flow rate was 1.0 mL·min-1
and the detection wavelength was set at 260 nm for pseudolaric acid B
230 nm for benzoic acid and salicylic acid. Result:The calibration curves were linear in the ranges of 1.29-25.78 mg·L-1(r=0.999 8) for pseudolaric acid B
0.022-0.266 g·L-1(r=0.9999) for benzoic acid and 0.011-0.110 g·L-1(r=0.999 8)for salicylic acid. The average recoveries (n=6) of pseudolaric acid B
benzoic acid and salicylic acid were 100.4%(RSD 1.00%)
100.9% (RSD 0.84%) and 100.5% (RSD 0.75%)
respectively. Conclusion:The developed method is accurate
convenient with good reproducibility that can be applied to the quality control of Fufang Tujingpiding.
